Dr. Bennet Omalu, the conrtoversial subject of the movie Concussion, went public with his suggestion of a ban on teenagers participating in high-impact sports. In a New York Times editorial, he wrote:

“If a child who plays football is subjected to advanced radiological and neurocognitive studies during the season and several months after the season, there can be evidence of brain damage at the cellular level of brain functioning, even if there were no documented concussions or reported symptoms. If that child continues to play over many seasons, these cellular injuries accumulate to cause irreversible brain damage, which we know now by the name Chronic Traumatic Encephalopathy, or C.T.E., a disease that I first diagnosed in 2002.”
